The folks at SFist have compiled the renderings for a complete Bay Bridge bicycle crossing. What’s your favorite design?

Option 1Option 2

A second option would be a similar cantilevered path, but with less obtrusive supports.
Option 3
Then comes the decision of where the path will touch down in San Francisco — and the closer you get to the waterfront, the greater the distance from ground to bridge. Thus you have the touchdown ramp up at the top which is enormous, because it would bring bicyclists off the bridge closer to the Embarcadero.
Touchdown Option 1: Essex Street
Touchdown Option 2: Caltrans Paint Yard

Another option involves a much bigger ramp structure that would touch down near Bryant and Beale on existing Caltrans property.
Touchdown Option 3: Embarcadero
As you can see, there’s a lot to consider, and none of this has been costed out. And let’s not even start on the inevitable fights about the aesthetics of this thing, especially if they start considering one of those enormous, highly visible ramp options.
Bicycle use on the Bay Bridge is projected at about 10,000 people per day, and that may not even be including 2,000 more who’ll be moving into new residences on Treasure Island.
So, even though this could take another 10 years and many millions of dollars, Renee Rivera ofBike East Bay tells KQED, “Even two years ago, I wouldn’t have thought we’d be where we are. It seems crazy to be excited about something that’s not going to happen for 10 years, but the thing is we’ve been working on this for maybe 25 years already.”
In fact, the Bay Area Toll Authority last did a feasibility study for a bike path in 2002.
First things first: They’re still hashing out the design of the eastern span connector to Yerba Buena Island, and construction on that may begin this year, or it may not.
